COMBINED METAL-BARREL COEEUGATING AND EDGING MACHINE.

Application filed February 14, 1919.

To all whom it may concern:

Be it known that l, Vroron C. Nononrs'r, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in CombinedMetal-Barrel Corrugating and Edging Machines, of which the following isa specification.

This invention relates to combined metal barrel eorrugating and edgingmachines, and has for its object to produce a ram actuated mechanism bywhich a metal barrel can be edged and corrugated in one operation of theram. A further object is to produce means for corrugating a galvanizedmetal barrel to greater diameter than the edgings for the ends of thebarrel, without injury to the galvanized surface or reducing thediameter of the barrel adjacent the corrugation.

Another object is to producemeans for rigidly securing a galvanized ironrolling hoop upon a metal barrel without affecting or fracturing orotherwise injuring the galvanized surface of such hoop or the galvanizedsurface of the barrel if the same is of galvanized material. A stillfurther object is to secure a reinforcing rolling hoop rigidly upon ametal barrel by producing a pair of external corrugations on the barrelat opposite sides of and against the hoop, as distinguished from themethod involving the heating and shrinking of hoops in place, as wheresuch method is employed it ren ders impracticable the use of galvanizedhoops.

WVith these objects in view the invention consists in certain novel andpeculiar features of construction and combinations of parts ashereinafter described and claimed; and in order that it may be fullyunderstood reference is to be had to the accompanying drawing, in which:

Figure 1, is a plan view of a ram-actuated mechanism for edging andcorrugating metal barrels in one operation of the ram or the like.

Fig. 2, is a central same.

Fig. 3, is a vertical section of a part of a barrel after the same hasbeen edged at one end and provided with a corrugation.

Fig. 4, is slightly modified construction whereby a galvanized rollinghoop can be vertical section of the Specification of Letters Patent.

tightly secured upon a barrel without the necessity of shrinking thehoop in position.

Referring now to the drawing, 1 is a suitable bed plate or support,surmounted by a ring 2 provided in its upper edge with a circular recess3, and with a plurality of vertical openings 4 opening into said recessand registering with corresponding openings 5 in the bed plate, thelatter also having another series of vertical openings 6, and acentral'opening 7 through which slidably extends the stem'8 of a ram forreciprocation by any suitable power. Below the bed plate the stem isequipped with a header 9 equipped with a series of vertical rods 10extending up through openings 4 and 5 and adapted when in normalposition, to project up into the recess 8, as shown in Fig. 2; said rodsbeing adapted at times to force a wedge ring upward from the bottom ofthe recess 3, for a purpose which herein-' after appears.

The header 9 is also equipped with a series of vertical rods 12extending slidingly through openings 6 in the bed plate and carrying attheir upper ends a combined circular wedge and retaining ring 13, thewedge face 14: of said ring being produced by forming a circular rabbitor groove at the lower end and inner side of said ring.

The stem 8 is equipped with a smaller combined wedge and retaining ring15 in the same horizontal plane'as ring 13 and bearing a concentricrelation to the latter, the wedge face 16 of ring 15 being formed byproducing a rabbit or groove in the outer face of said ring in the samehorizontal plane as the wedge face 14 of ring 13jthe said rings 13 and15 being of such size that they shall be capable of sliding downwardupon the outer and inner sides of ring 2 when the ram stem movesdownwardly.

Arranged concentrically of the stem upon the supportin ring 2 are innerand outer sets of dies 1? and 18, the former having an outwardlyprojecting circular flange 19 and a circular recess 20 just above saidflange, and the outer sets of dies a circular recess 21 to receive theflange 19 and an overlying inwardly projecting flange 22 to enter therecess 20, each die of the sets therefore constituting a male dieand afemale die, the dies being so'proportioned that when spread apart orwithdrawn from each other the outer edge of the flange .19 shallslightly overlap the inner edge of the bottom of the recess 21 of thecompanion die,

of flange 19 a distance slightly exceeding the thickness of the metalbarrel to be edged and corrugated, as hereinafter more particularlyreferred to, the dies being also so proportioned that when forcedtogether to perform the edging operation, there shall be an open jointbetween them susceptible of receiving the extreme upper edge 011 pointof a spreader ring 23 fitting slidingly in the recess 3 of supportingring 2 which spreader ring is adapted to be forced upward bythe'underlying rods 10 when the ram stem moves upward, to effect theopening or separating movement of the dies 1? and 18, as shown clearlyin Fig. 2, the said spreader ring dropping by force of gravity orbeing-forced downward by the approaching movement of said dies when theram stem moves downward.

The dies are so proportioned that the inner ones in moving outward willbecome slightly spaced apart and in moving inward will abut togethersidewise, the reverse operation occuring with respect to the outer dies,that is in moving inward they approach each other and in moving outwardbecome slightly more widely spaced apart, as will be readily understoodby reference to Fig. 1, it being understood that the approachingmovement of the dies is accomplished by the pressure thereon of the camsurfaces 1d and 16, and that the reverse movement of the dies iseffected as stated, by the said spreader ring, it being also noted byreference to Fig. 2 that the operative or closing movement of the diesbegins in the initial part of the downward movement of the ram stem, andthat the reverse movement of the dies is accomplished as the up wardmovement of the ram stem is ending, and that in the interim betweentheinitial downward movement of the ram stem and the ending of theupward movement thereof, the parallel adjacent faces of the wedge rings13 and 15, retaln the dies in their i closed or operative positions,that is with the flange or male members 19in engagement'with therecesses or channels 21, and r the flanges or male parts 22, inoperative relation to the recesses or channel parts 20;

Mounted upon the inner dies 17 and snugly embracing the inner wedge ring15 and retained in concentric relation by said parts, is a secondsupporting ring 24:, the same being widened at its upper end by theprovision of an inwardly projecting flange 25, the ex ternal diameter ofthe supporting ring 24 standing in the vertical plane of the outer edgesof the'fianges 19 of the in- .ner dies, when thelatter occupy theirinnermost or ino erative osition.

Secured upon the ram stem is a frustoconical wedge 26, which when saidstem is at its highest point of adjustment, fits with lts lower endwithin a circular series of corrugating plates 27 rounded at their outeredges as at 28 to produce a corrugation of and then pressed downwardlyin the latter a so that upon retracting it will retain its position inthe grooves and exert inward pressure on the said plates and normallyhold them with their rounded outer edges in approximately the samevertical plane as the periphery of the supporting ring 24.

Assuming that the operative parts of the mechanism are in the positionshown most clearly by Fig. 2, it will be apparent that metal barrel 31of proper size can be ranged in the position shown in said figure, andthat when so arranged downward movement of the ram stem will through theaction of the wedge rings 13 and 15 close the dies 17 and 18 and thusform on the lower end of the barrel a right angle shaped edgbig 32, thevertical portion of which is ofii 7 set inwardly sightly from the innerwall. of

the barrel, this edging being adapted in a manner well-known in the artand therefore not shown or described, to be seamed and sealed onto abarrel head, not shown, to secure the latter firmly in position with aliquid tight joint, the joint being made secure ordinarily by means of achime also not shown as forming no part of this invention. 'As theedging of the barrel is accom,--

plished, the spreader ring 23 drops or is forced downward into therecess 3, this action occurring because the rods 5 move downward withthe header 9 and the said wedge rings 13 and 15. As the edging operationis completed, the adjacent parallel faces of the wedge rings retain thedies in their operative position with the lower end of the barrelclamped between them, and by the time the edging operation is completedthe wedge 26 begins to impart simultaneous outward movement to thecorrugating plates 27 to cause the same to gradually bow outwardly theopposingportion of the body of the barrel until the downward movement ofthe ram is ended by which time said outward bowed portionof the body ofthe barrel constitutes a corrugation 33 of diameter appreciably largerthan the maximum diram stem is reelevated to permit the spring 29,expanded by the downward movement of wedge 26, to retract andwithdraw'the corrugating plates to normal position, and as the upwardmovement of the ram stem is ending, the spreader ring is reelevated bythe bolts 10, to spread open or apart the said dies 17 and 18, andpermit the barrel to be removed and then replaced in inverted positionso that upon the next reciprocation of the ram stem, the other end ofthe barrel shall be edged and a second corrugation be formed in thebarrel.

In Fig. l appears a corrugating plate 34 forming one of a series ofcorrugating plates arranged and operated in exactly the same manner asthe corrugating plates 27, but each provided at its outer edge with twosma l rounded peripheral ribs 35 instead of having one rounded outeredge 28, which ribs 35 are spaced apart and parallel with each other. Inthis construction the plate is provided with a pair of inwardlyconverging grooves 36 instead of a single groove 30 as in Fig. 2, andtwo springs 37 corresponding to spring 29 are preferably employed foreffecting inward movement of the segment plates 34, although it isobvious that a single spring could be employed to perform the functionof the two springs shown.

When the ram is moved downward to effect outward movement of the plates3a, a pair of corrugations 38 are formed on the barrel. Thisconstruction is adapted for securing upon the barrel what is known as areinforcing rolling hoop 39, the same being supported in any suitablemanner in proper position with respect to the ribs 35, so that when thelatter produce the corrugations 38 on the barrel, they shall clampagainst opposite edges of roller hoop and thus secure the same firmly inposition. Heretofore, it has been customary to heat reinforcing rollinghoops and then shrink them upon the barrel, this method necessitatingthe use of hoogs of black iron or other material and thus inhibiting theuse of galvanized iron. By my eons ruction as described the rollin hoopmay be of galva-nized metal, and it is secured in posi tion with thenecessary firmness and rigidity and without any tendency of checking orfracturing'the galvanized barrel or hoop.

Furthermore it can be so secured in position more quickly and at lesscost than by methods hereintofore used, and in this connection it isdesired to state that the formation of corrugations on galvanized metalbarrels through the use of a series of radially adjustable corrugatingplates, facilitates the work of corrugating and enables the corrugationsto be of sufficient depth without injury to the galvanized surface ofthe barrel, to facilitate the upending of the barrels from a proneposition upon the ground, it being well to state in this connection thatone of the reasons for making the barrel of greater diameter at thepoints of'corrugation than at the ends, is to enable a man to upend abarrel more quickly and with less exertion than where the leverage ofthe full length of the barrel must be overcome in upending it.

From the above description, it will be apparent that I have produced acombined barrel corrugating and edging machine which embodies thefeatures of advantage enumerated as desirable in the statement of theobject of the invention, and which is susceptible of modification invarious particulars without departing from the principle of constructioninvolved or from the spirit and scope of the appended claims.
